CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a 371 of International Application No. PCT/KR2018/008773 filed on Aug. 2, 2018, which claims priority to Korean Patent Application No. 10-2017-0110942 filed on Aug. 31, 2017, the disclosures of which are herein incorporated by reference in their entirety.

BACKGROUND 1. Field

The present disclosure relates to a vacuum cleaner, and more particularly to a vacuum cleaner capable of enhancing the convenience of use with an improved handle structure.

2. Description of Related Art

In general, a vacuum cleaner is a device capable of performing cleaning by generating a suction force and sucking foreign substances such as dust together with air and then removing the foreign substances using a dust collector and the like provided inside a main body.

The vacuum cleaner is mainly classified into a canister type and an upright type. The canister type cleaner includes a main body in which a blower, a dust collector, and the like are mounted, a suction nozzle installed separately from the main body to suck dust from a floor, and a connection pipe to connect the main body and the suction nozzle.

Therefore, a user performs cleaning while holding a handle installed to the connection pipe and moving the suction nozzle in a direction to be cleaned.

In particular, the user may operate the vacuum cleaner by pulling the handle of a trigger type with a finger. The user turns the vacuum cleaner on or off by grasping a handle grip with the hand and pulling and releasing a trigger provided at a position where an index finger touches.

However, the trigger type vacuum cleaner is inconvenient in that the user needs to keep pulling the trigger throughout the cleaning.

In addition, the trigger type vacuum cleaner is cumbersome in that a button for adjusting the suction intensity of the cleaner is separately provided so that the user needs to adjust the suction intensity by using a hand other than the hand holding the handle, which may be a factor that lowers the cleaning efficiency.

SUMMARY

The present disclosure is directed to providing a vacuum cleaner capable of enhancing the convenience of use by improving the handle structure.
